c - g++ Mac Curl 架构 x86_64 的未定义符号

Question

我正在学习与 curl 相关的在线课程。但是，我遇到了一些问题。

我的建筑声明是：

gcc -Wall web-server.c -o web-server1 -lcurl

这是 web-server.c 中的代码

#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>
int main(void){
    CURL *curl = NULL;
    CURLcode res;

    curl = curl_easy_init();

    curl_easy_setops(curl, CURLOPT_URL, "http://www.google.com");


    res = curl_easy_perform(curl);
    if (res != CURLE_OK){
        print("curl easy perform error res = %d",res);
        return 1;
    }

    curl_easy_cleanup(curl);
    return 0;
}

错误信息是：

Undefined symbols for architecture x86_64:
  "_curl_easy_setops", referenced from:
      _main in web-server-afa9ad.o
  "_print", referenced from:
      _main in web-server-afa9ad.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

非常感谢你们 我的操作系统是 MacOs 10.14.6 我的 gcc 版本
